Needle punched non woven geotexile is a needle-punched staple fibre nonwoven geotextile made of PP or PET fiber, some products additionally calendered, used as protection,separation, filter and drainage geotextile.

Application ：

It is used in many fields of civil engineering including hydraulic engineering, landfill engineering, road construction and tunnel construction. As a separation geotextile.

It prevents individual and distinct granular layers from contaminating one another. Thus, structural fill and base courses maintain their integrity for a substantially longer period of time than otherwise possible. When fine soil layers are present next to drainage layers on highway or railway construct ion projects.

Its functions as a filter preventing fine soil particles from washing through and com promising the drainage ability of the coarser layers. Displacement of small amounts of water in problem areas is facilitated by the in-plane transmissivity. 

It with a high mass per unit area can also protect geomembranes or pipes against mechanical damage. If necessary, a woven geotextile can be integrated into the matrix of  geotextile  to distribute dynamic loads and thus augment its protective abilities.
